Apologies for what may be a dumb question, but do all 105 gearboxes require the gear shift to be pushed down/in to shift into reverse, or is this just an early or late gearbox feature?

Just the early ones - you can fit a push down lever to a later gearbox with the automatic 5th/reverse lockout though - Mine is setup that way. Pushing it down doesn't do anything - but it looks right :)
Hi Scott,
Do you happen to know if a later model shift assembly can be bolted straight onto a gearbox which originally came with a pushdown shift assembly?
I'm trying to make up one good gearbox from about two and a half spare gearboxes, one of which has the pushdown shift but is also missing the actual pushdown shift lever.

I might have a spare push-down if you need one - they're getting a bit thin on the ground, that's for sure. (and they can be buggers to get apart if you do have one that needs restored..)
You can fit a late lever without the pushdown to an early box - but I'm not 100% sure if you can replace the push-down interlock in the neck of the box with the auto-lockout interlock from a later box to match it. worst case you could remove the lockout completely - and just give the teeth a clean now and again going from 5th to 4th :)
It's pretty easy to take the vents off the turret of the gearbox and remove the lever joint - swap it and the interlock plate with the spring over and see how it goes... the vents have shim rings that centralise the lever joint in the gate - you might have to muck around with these to get it smoothly returning to the middle 3rd/4th area of the gate, and not bind against the 5th/reverse interlock....
Good fun:)
Cheers,
Hi Scott,
What I was getting at may be best described in the below diagram. Assuming part "A" is a gearbox which originally came with a pushdown shift version of part "B", could you just replace the pushdown shift version of part "B" with a later model (ie non-pushdown shift) version part of "B"?
In other words, can you graft a later model shift tower and housing onto an earlier model gearbox?
Thanks for your help on this.
Regards,
Nick
Oh...
I'm not sure :) I have a niggly thought about the size of bearing(s) in the back of the tower being different - and/or that they may be shimmed to a clearance during assembly of the split case / turret... - but that may all be based in fantasy :)
Vin Sharp would be the first person I'd personally think of to ask that question.
If this just to get the later lever / lockout I'm pretty sure it will be easier to migrate the upper part of the mechanism in the turret - But if you need to make a full gearbox out of differing series parts that might be a measure as you go process :)
Sorry if that's not particularly helpful :)
Cheers,
